ABSTRACT:
A pneumatic wrench includes a pneumatic motor, a striking mechanism, and a drive shaft. The striking mechanism includes a support seat, a cam, a cover, and a hammer. Thus, the pivot shaft of the hammer has two opposite sides each formed with a reinforcing rib to reinforce the structural strength of the hammer. In addition, each of the first pivot shaft and the second pivot shaft has a guide groove to overcome the shear stress applied on the hammer during the rotation striking process of the hammer, thereby preventing the hammer from being distorted or broken due to concentration of a stress so as to enhance the lifetime of the hammer.
